Choosing a 6 and then a prime number

Choosing two odd numbers

Answers

Answer 1

Answer:

Answer:

Choosing a 6 and then a prime number:2/21

Choosing two odd numbers: 2/7

Step-by-step explanation:

Choosing a 6 and then a prime number:

The probability of choosing 6 out of 1, 2, 3, 4, 5, 6 and 7 is one event divided by number of total events (which is equal to 7). That results in 1/7. Once 6 is chosen, the probability of choosing a prime number (prime number is a number that can only be divided by 1 and itself) out of 1, 2, 3, 4, 5 and 7 is 4/6 (prime numbers are 2, 3, 5, 7 in total there are 4 number and total number of events are 6). Finally, the probability of choosing a 6 and then a prime number is (1/7)*(4/6)=2/21.

Choosing two odd numbers:

The probability of choosing 1st odd number is 4/7 (number of odd numbers is 4 which includes 1, 3, 5, 7 and the number of total events is 7). Once 1st odd number is chosen, the probability of choosing 2nd odd number is 3/6 (number of odd numbers is 3 - because 1 odd number is already chosen and the number of total events is 6). Finally, the probability of choosing two odd numbers in a sequence is (4/7)*(3/6)=2/7.

Answer: B) 64/9

Step-by-step explanation:

8/3= 2.666666667

2.666666667^2= 7 1/9

7 1/9 equals to 64/9 which therefore gives the answer choice B.

Answer:B 64/9

Step-by-step explanation:

x to the power of 2 : x * x

8/3 to the power of 2 : 8/3 * 8/3 = 64/9

Jarret walks his puppy outside every day for 30 minutes. Angela walked her puppy every day for 90 minutes. Find the number of minutes that each puppy was walked for 1, 2, 3, and 4 days. Then graph the results as ordered pairs. How many more minutes does Angela spend walking her puppy over 2 days compared to Jarret walking his puppy over 2 days?

Answers

Answer:

Read the answers below, including the graph.

Step-by-step explanation:

1. Let's find the number of minutes that each puppy was walked for 1, 2, 3, and 4 days.

Day 1 Day 2 Day 3 Day 4

Angela 90 180 270 360

Jarret 30 60 90 120

Ordered pairs for Angela's puppy: (1,90); (2,180); (3,270); (4,360)

Ordered pairs for Jarret's puppy: (1,30); (2,60); (3,90); (4,120)

2. How many more minutes does Angela spend walking her puppy over 2 days compared to Jarret walking his puppy over 2 days?

180 - 60 = 120

Angela spend walking her puppy 120 more minutes over 2 days compared to Jarret

Olivia ties 2.5 feet of ribbon onto one balloon. How many yards of ribbon does olivia need for 18 balloons

Answers

$1yd=3ft\to1ft=(1)/(3)yd\n--------------------\n2.5ft\to1\ ballon\n\ntherefore\n\n18*2.5ft=45ft\to18\ ballons\n\n45ft=45*(1)/(3)yd=\boxed{15yd}\leftarrow answer$

Answer:

15 yards of ribbon does olivia need for 18 balloons

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity 1 such as 4 meter per seconds or 5 miles per hours.

As pert the statement:

Olivia ties 2.5 feet of ribbon onto one balloon.

⇒ $\text{unit rate per balloon} = (2.5)/(1) = 2.5$ ft ribbon

Use conversion:

1 feet = 1/3 yard

then;

2.5 ft = 0.833333333 yard

⇒ $\text{unit rate per balloon} = (2.5)/(1) = 0.833333333$ yard ribbon

We have top find how many yards of ribbon does olivia need for 18 balloons

$\text{Number of ribbons} = \text{Unit rate per balloons} * 18$

Substitute the given values we have;

$\text{Number of ribbons} = 0.83333333 * 18 = 15$ yards

Therefore, 15 yards of ribbon does olivia need for 18 balloons
